Lego Ball Bearings 

The metal or steel balls have item number 99948 and are from the Mindstorms EV3 Set (45544).

I’m actually kind of amazed at how low-friction that is.

I'm excited to have seen this 8 seconds after release.

観覧車とかの作品が増えそうだね

Cool new part! Can't wait to see how this will feature in GBC modules...

I was waiting for someone to use the new technic rings from the latest Lego Friends Wave for something cool and you definitely delivered:)

軌道輪，転動体，保持器とベアリングの要素を完全に再現しててたまげた 転がり摩擦もかなり小さそう

Gravity powered clocks just got more efficient

Very useful, well designed!

Wow! What a perfect wheels and casing size...

Your builds always continue to amaze me, :).

レゴにすることでベアリングの仕組みがめっちゃわかりやすい

小2の息子が科学技術館に展示されているベアリングを見て、「夏休みの自由研究はベアリングにする!」と言い、難しいテーマなのでサポートする親としては頭を悩ませていましたが、レゴでベアリングが作れるとは! 参考にさせて頂きます

Amazing stuff. As always, nice choice of colours.

How can someone even come up with this. It’s just mind-blowing to me🤯

新いものもつかって、素晴らしいイマジネーション

That's awesome!!

Thank you for putting english subtitles on the video

Finally the perfect way for me to make a giant Lego fidget spinner

Looking forward to a sweeper module showing off this mechanism🙂

Pretty good!

レゴにこんな部品があるのを初めて知った！

Ooo, spinny! And clever!

Absolutely love this content.

What a nice bearing

ABEC 0.00001 nice work! :)

Mr. Akiyuki, you are a true engineer sir.

ベアリング入りのホイール使って動力付き自動車作ってみたら面白そう

公式に取り上げて欲しい…

Don't mind me, just casually making A wheel of Fourtune with nothing but Legos

your a wizard

これをたくさん作れば駆動音が静かな装置が作れますね！

Very nice

this is a very good experiment with lego ball bearings

this is so good you have no idea

Nice!!!

Wow I never knew Lego made metal balls.

If it exists, you can legofy it.

Now this video is satisfying

From the lego friends set! I got one yesterday purely for these rings.

Wire it up and turn it into a power plant. That would be amazing, lolz

I wonder if you could use the yellow ring to make a real good helicopter swashplate setup.

Brilliant.

Awesome

can you please also post the part numbers of the middle parts? I haven't seen them before either

Looks like... Everyone love this idea of Fidget spinner's

I will try glass marbles.

I'm a simple man, I see Akiyuki, I thumb up.

Were these parts designed with these tolerances for this reason, or is it just a coincidence?

初コメです。 機械にもレゴにも詳しくないのですが、なぜか惹き込まれます… 他の動画を先に何本か見ましたが、美しいですね(*´ω｀*)💕 そしてコメント欄の日本語の少なさにびっくりです💦 すごいのに！！

What kind of set uses the metal ball bearings?

like butter! KEvron

It's a spidget finner

Sei un fritto!

Why am I here? Hey, this is kind of neat. PRAISE THE RU-vid ALGORITHM!

what set do the new parts come in?

are those all real lego pieces?

これは掛け時計として使用できるようです

would like a slippery graphite powder help reduce friction more.. or cause more friction?

Is that center peice custom

do you have the reference for the central piece please?

You could make a cool fidget toy with out of this...

fidget spinner time lol

車とか作れそう

If round is repelling middle(neodymium magnet) maybe can be faster spin?

Wow

金属パーツが公式に存在するのを初めて知り笑った

I haven't ever seen both of the circular technic pieces in my life, anyone know where they're from?

Lego fidget spinner?😳

2:48 friction based planetary gears

Don’t forget to grease after installation

Lego Fidget Spinner

こういうのができるのを見てしまうと たとえおもちゃでも部品設計はかなりタイトにやってるのかなと思えてくる シールはさすがに難しそうですか？…と思ったらすぐに出てきて草

用途がルーレットw

What's the gray central part from the first bearing?

保持器まで。。。感心

Are those lego soccer balls?

what are those small shiny loop things put in between the small pieces and the second ring seen at 0:12

人　生　ゲ　ー　ム！

oh god my childhood god is back! Please notice me as you shaped me as a person.

Subarashii

You cannot convince me that LEGO didn't have this in mind when they created that new part. ;-)

Now to just make a giant lego fidget spinner

has anyone worked this into an RC build?

Ok

ハンドスピナー作れるやん

Lego fidget spinner

2:29

油吹いたらとても滑りそう

So… a fidget spinner?

Hi

Posted 8 seconds ago

now put that bearing inside of another bearing

The balls harden

おほー？

OH............... MY.................... GOD................................................................................................................ how long before Akiyuki hits 10,000 rpm???????? ............just a light spray of lube to prolong the life of the LEGO ABS and GO.............................................................

0:06 WAT?

ねえ、あなたのビデオが大好きです、あなたもインスタグラムを持っていますか？

🤤🤤🤤

What new part? it's not on newelementary. Akiyuki do you secretly work for lego and you just haven't told us
